The mechanism of the cash register forming the object of the present invention is 50 mounted on two parallel frames or cheeks 0. 87,352, and in France February 20, 1925.

9798 supporting the different spindles thereof.

Every operation is performed in causing the shafts c and Zto make a full turn in known manner, this being obtained through the operating handle 31 and the gears 9l011.

It is submitted that the operation of Fig. 3 is clearly set forth on page '7, lines 8 and the following which describe in coanmon Figs. 3 to 9.

Every set of keys'is located, through the represented means, so that the keys which have been acted upon are maintained down until the operation is finished, all the keys of a set being locked when one of them has been depressed. The depression of a key causes the rod 15 of this key to shift towards the interior of the machine. 115 is a false key which normally projects in-v wardly but which is urged outwardly when one of the keys of the same set is depressed.

Qpposite each vertical set or row of keys is mounted, upon the shaft (Z, a mechanism composed of the following parts which are arranged side by side (Figs. 1, 2 and 8 to 12).

1. A cam 18 is fixed to the shaft (Z.

2. A plate 19 is loosely mounted on the shaft (1. On the side of this plate and facing the cam 18 is mounted a latch 20 conveniently guided which, under the action of the spring 21, tends to enter by its end into a corresponding notch 18 provided in the periphery of the cam 18 but can be relieved therefrom by means of the plate 23 pivoted at 28 upon the other face of the plate 19 and controlling through a holeprovided in this plate a stud 20 connected with the said latch. Upon the plate 23 is pivoted at 22 a tappet 22 the nose 22 of which, in the alternating revolving motion of the plate 19 which will be hereinafter described, is shifted towards the ends. of the rods 15 of keys 15, but to such a small extent as to meet the one of these rods which has been pressed and locked as above indicated. A spring 22 attached to the second arm of said tappet 22 always causes the elastic lifting of the nose 22 therefore when a key 15 is depressed, the tappet 22 recedes in passing against the stem of this key, when the plate 19 is moving according to the direction indicated by the arrow :1; but when moving in the opposite direction (arrow 3 the tappet 22 catches the stem of this key, thereby causing the plate 23 to oscillate about the point 23 and the latch to raise.

A lever 2a articulated at 245 to the plate 19 is urged by a spring 2 1 so as to always bear against the heel 23' of the plate 23 so that, when this plate oscillates as just described, the lever 24lturning about its pivoting axis 21 is pushed back towards the shaft (Z.

8. A plate arranged independent from the shaft (Z, but in afixed position, this plate carrying a lug 25 engaged with a fixed rod m. This plate 25 is provided on a part of its periphery with teeth of an angular shape into which can enter the nose i of a corresponding shape of the lever 21.

4. A toothed wheel 27 is loosely mounted on the shaftv (Z and has a number of teeth which is a multiple of ten, for example, in the case represented, teeth. \Vith the teeth of this wheel meshes the spring detent 28 carried by the plate 19.

5. A wheel 40 connected with the toothed wheel 27 and has one tenth the number of teeth of the wheel 27, consequently five teeth in the example represented.

The shaft (Z to which the cam 18 is fast carries at one of its ends an arm 16 which is articulated to the link 17 connected on the other hand vith the crank 117 keyed upon the axis 0. The said arm 16 being larger than the crank 117, it results therefrom that a revolution of the spindle 0 will impart to the shaft (Z a to and fro revolving motion the angular amplitude of which must be, at the top and at the bottom, a little larger than the sector occupied by the keys.

In its waiting position or position of rest, the cam 18 occupies such a position that the notch 18 of this cam will correspond, to the latch 20 in the outmost upper position of the plate 19. \Vhen in the first part of an operation the cam 18 revolves in the direction indicated by the arrow w, the periphery of this cam slides against the end of the latch 20 until the notch 18 comes opposite this latch in the position in which it has been left at the preceding operation. The said latch 20 entering said cam 18 is then carried along and with it the plate 19 which moves in turning about the shaft (2. In this movement, and as it has been hereinbefore specified, the tappet 22 recedes in front of the end of the key which has been previously pressed. The plate 19 is thus brought to the bottom of its stroke, then as the cam 18 carries the same along in the return motion of the shaft (1 this plate raises again. -During this ascending motion, (arrow 3 the tappet 22 abuts by means of its nose 22 against the stem of the key which has been pressed. The plate rocks and causes the raising again of the latch 20 which escapes the notch 18 of the cam 18. Therefore, the latter continues its movement without driving the plate 19. But this plate 19 in raising again has driven by means of its detent 28 the wheel 27 which has thus been moved according to a number of teeth corresponding to the key which has been pressed, the distribution of the keys of every vertical set being made according to the division of the toothed wheel 27. As the keys are numbered in starting from the bottom, it results therefrom that the whee 27 will have turned three teeth when the tappet 22 has struck the stem of the key 3 pre viously depressed, or of any other number of teeth corresponding to the figure indicated by the depres ed key.

Now, the toothed wheel 27 drives, by means of the intermediate gearing 29, the ten-teeth pinion 30 fast upon the shaft 9 of the totalizer, which comprises, close to the said pinion 30, a milled wheel 101 carrying the ten figures and which therefor advances, at every operation, according to a. number of Civisions corresponding to the digit of the key which has been depressed.

\Vhen no key has been depressed in the vertical row, the false key 115 has remained in its projecting position and it is against the same that bears the tappet at the very beginning of the ascending stroke of the plate 19. The latch 20 being then released at the very beginning of this stroke, there will be exerted no action, neither upon the wheel 27 nor upon the totalizer.

A spring detent or pawl 26 mounted upon the spindle m prevents the toothed wheel 27 from returning, the latter being new capable of turning only in the direction of the totalization.

At every stopping of the plate 19 due to the striking against the stem of one of the keys, the lever 24 being pushed by the heel 23 of the plates 23, the nose 2% of this lever enters into the angular teeth of the plate 23 which, as it has been seen, is fixed and determines in this way the exact position of the oscillating plate 19.

On the opposite side to the keys the plate 19 is provided with teeth 19 meshing with the pinion -18 on the end of a sleeve loosely mounted on the spindle e and carrying at its other end a spur wheel 19 which meshes with a corresponding wheel 49 serving to drive the printing discs, not forming part of the application.

The indication of the amount is displayed exteriorly by the rotary indicator controlled by means of the small link 34 articu lated to the plate 19, the quadrant 32 and the pinion 33.

It has been observed that at every operation, every milled wheel of the totalizer is moved forward according to a number of divisions equal to the figure of the corresponding key of the same group of parts. Thus when a wheel has come to the figure 9, it is nec essary that, as soon as it will move forward of one division, the number of units of the higher order will be increased of 1. This result is obtained by means of the following arrying over device (Figs. 1, 13 and 14). Upon the spindle f are loosely mountthe lovers 42 each one of which corresponds to one of the groups of wheels which have been previously described. Everyone of these levers comprises on one side of the spindle an arm 42 the nose 42 of which lies in the same plane as a five toothed wheel 40 of one of the groups of parts and another arm- 42 which carries a detent 45 meshing with the fifty toothed Wheel 27 of the group corresponding to the units of the immediately higher order. On the other side of f, this lever carries an arm 42 the end of which, out according to the slants 42-42 forming together a notch 42?, is in mesh with a spring pusher 43 mounted upon a stationary cross piece 44. When the totalizing wheel of the group in consideration comes to the digit 9, a tooth of the wheel 40 has come against the nose 42 of the lever 42 the position of which is maintained by the fact that the end of the pusher 43 is engaged in the notch 42 45 is in gear with the teeth of the wheel 27 of the group corresponding to the units of the higher order. Now, when in the course of a new operation, the wheel of the totalizer of the group in consideration is moved forward of one division, the tooth 41 pushes back downwardly the nose 42 and causes the lever 42 to revolve about its axle f, this movement being facilitated and accentuated by the fact that the pusher 43 slides over the slope 42/ of the end of the arm 42. In this movement, the detent 45 has been disengaged from the teeth of-the wheel 27 and has assumed the position indicated in dash and dotted line 3 (Fig. 13), this position being fixed by a spring 45 which tends to raise the detent 45 and by the fact that the pin 45 mounted on this detent strikes against a stop 45 limiting its raising motion. At the beginning of the following operation, the cam 47 keyed to the spindle 0 acts upon the roller 42 mounted upon the heel of the arm 42 and lifts the lever the detent 45 of which coming in gear with the teeth of the wicel 27 of the following group (figures of the immediately higher order) causes this wheel to advance of one tooth. Thus a unit of an order immediately superior to the one of the considered group is registered on the totalizer.

A cam 47 corresponds to set of keys. In

At this moment the detent order that the carrying over operations may take place successively unit after unit, starting from the. lowermost unit, the cams 47 are slightly shifted or displaced the one with reference to the other upon the spindle 0, so that they will act successively the one after the other for producing the carrying over effects which have just been described.

The machine being thus used for registering the operations such as expenses or sales on credit which are not added in the receipts, has a disengaging mechanism which enables the disengagement of the totalizing mechanism when one of these operations has been made. the roller 148 mounted upon the lever 120 for setting to expenses or sales on credit acts in these positions of the said lever 120 upon the arm 149 keyed upon the axis p in order to cause this axle p to revolve, the same extending over the whole length of the machine and carrying, opposite every group of totalizing members, a sector 150. In the normal position of this sector 150 (position represented in the drawings), the external edge is a little inside the are through which travels the finger 151 secured to the end of the rod of the driving detent 28 of the totalizing wheel 27 in such a manner that this sector 150 will in no way hinder the action of this detent 28 nor the whole of the totalizing motions which have been hereinhefore described. But, when according to the partial revolution of the axis 39 which ias just been mentioned, the sector 150 is shifted in receding from the center of the wheel 27, its external edge is displaced inwardly to an extent which is a little superior to the engagement of the detent 28 with the teeth of the wheel 27 so that this sector 150 acting under the finger 151 will lift the detent 28 and disengage the same from the above mentioned teeth which thus are not driven along during the displacement of the totalizing parts. of the sector 151 are such that the same secures the effect which has just been described whatever the position of the detent 28 may be and over the whole course of the latter.

I claim:

A cash register with vertical sets of keys, comprising in combination for each vertical set of keys a main shaft of the machine, a

toothed wheel keyed on said shaft, a plate loosely mounted on said shaft, a spring detent carried by said plate and engaging in said wheel, means for actuating said detent to shift said wheel a number of divisions corresponding to the key the rear side of said detent, an intermediate axle of the machine, a sector keyed on said axle with its free end extending under said nose irrespective of the position of said detent, an arm keyed on said axle, a lever For this purpose (Fig. 10)

The form and amplitude 1 depressed, a nose on keyed on said shaft, a tappet on said lever, and means for operating said lever to cause said tappet to act on said arm to lift said sector and said detent.

5 In testimony whereof I affix my signature.
